It has been warm and humid across the South and Southeast as of late. This has left many people wondering when fall will arrive. To answer the question: soon–at least temporarily. A potent upper-level storm system out west will slowly move east throughout this week. That storm system will send a cold front south into the Southern Plains in a few days, followed by the cold front sneaking east into the South and Southeast late this weekend into early next week.
Temperatures will fall below average across the region from October 17 through October 19. Morning temperatures will actually be quite chilly! See the timing of the cold front, how long the cool air will stick around, and how low temperatures will go.
